SETI, Imagining Extraterrestrial Civilizations, and War

In the three-way horse race to prove that biology is not just a terrestrial aberration, there's one steed that many people ignore: sampling the air of distant planets to see if they contain the exhaust gases of life, or in the jargon of astrobiologists, biosignatures.

Is Active SETI Really Dangerous?

John W. Traphagan | Posted 03.01.2016 | Science
John W. Traphagan

Perhaps a more important question is not about the risks of transmitting, but the dangers in receiving. Many in the SETI community have shown commitment to the belief that a technologically advanced civilization will be altruistic, despite the lack of evidence supporting that assumption. Therefore it is assumed there are no significant risks with listening quietly.

In an interview for Business Insider, astronomer and former director of the Center for SETI Research Jill Tarter, responded to Stephen Hawking's concerns about Active SETI, or sending messages to possible extraterrestrial civilizations rather than simply waiting and listening for signals from said intelligent aliens.

We have discovered that neither our place in the galaxy nor our galaxy itself is special. The discovery of extrasolar life will demonstrate that that claim to being special will have to be abandoned.

UFOs: The Trail Is Stale

Seth Shostak | Posted 09.01.2015 | Science
Seth Shostak

The extraterrestrials are just plain done with us. The Cold War has ended, and so has their fascination with our nuclear missile silos. So maybe they've just declared "mission accomplished," and gone away. That would be analogous to Charles Darwin's visit to the Galapagos Islands -- after he probed, bottled and cataloged some of the natives, he weighed anchor and withdrew. But here's another possibility.

ET, the Deafening Silence

We choose to search for extraterrestrial life and intelligence because as Americans, we are free, permissive, non-conformist, incorrigible, and preoccupied with our choices.

With this discovery, we come ever closer to the idea that life is common in the universe. Perhaps you are not convinced. That is OK; let me speculate what would happen should we ever find evidence of life beyond earth even if you think such discovery unlikely.

Why the Earth Will Never Be Invaded

Robert Lanza, M.D. | Posted 05.17.2015 | Weird News
Robert Lanza, M.D.

Cosmologists propose that the universe was until recently a lifeless collection of particles. But they have ignored a critical component of the cosmos because they don't know what to do with it. This component, consciousness, is an utter mystery. How did inert, random bits of matter ever morph into Obama or Lady Gaga?

Klingon Worlds

It seems that the frequency of planets able to support life is roughly one percent. In other words, a billion or more such worlds exist in our galaxy alone. That's a lot of acreage, and it takes industrial-strength credulity to believe it's all bleakly barren.
